Teleport to the Tavern Lobby anchor in Planarcadia’s World’s End Tavern. After spawning, walk straight towards the bar counter. There, you will see Sampo standing on the left side. Talk to him to start the mission.

Defeat Umbralle in Dovebrook District

First off, teleport to the Furbobo Weekly Editorial Headquarters Space Anchor in Dovebrook District. Then, walk down the stairs and turn right. After reaching the end, take a left turn where you’ll see Umbralle standing near a store with a giant disco ball. Go close to the NPC and interact to initiate the battle.

Since Umbralle is level 5, make sure to use a card that can easily beat the opponent. In this case, the best choice will be Firefly. Moreover, you can “Gild” the card to increase your chances of winning.

While fighting, make sure to select dice with the highest numbers. When you attack, this will boost your damage. As for defending, it will allow you to negate the corresponding damage dealt by the opponent. If you roll low numbers, make sure to reroll, as you will get plenty.

Defeat Magical Middleager

For this particular enemy, you must go to Graphia Academy using the Academy Atrium anchor. When you spawn, turn right and head towards the stairs. The opponent will be standing right beside the stairs.

Unlike the previous one, defeating Magical Middleager will be quite easy, as this adversary is only level 3. Same as before, use the Firefly card to fight this opponent. Regardless of whether you are attacking or defending, select the dice with the highest numbers.

Moreover, you can also try to activate the card’s power by making sure there are at least two pairs of the same number. Since the Enemy has a low HP pool, you can defeat them in very few turns.

Defeat Kendor

Teleport to the @EntertainmentPlaza anchor in Duomension City and head south. When you reach a small food cart, turn right and walk up the stairs. On top, you’ll see Kendor on the left side. Interact with him to start the battle. Once again, using Firefly is the optimal choice since the opponent can only choose three dice while attacking and two when defending.

During your attack turn, make sure to deal as much damage as possible to quickly deplete the adversary’s HP. When you do so, start heading to the last challenge.

Defeat Singafar

Go to World End Tavern’s Lobby. Turn left when you reach the bar area and interact with Interplanar Jump! Difficulty II. Traverse the area to go to the other side, then head up. There, you will see Singafar standing near the railing.

When you start fighting, make sure to use the Prismatic Dice while attacking to make the most out of it. If you end up getting max rolls on three dice twice, you can defeat the adversary in two turns.

Defeat Dinocto

After defeating all four adversaries, head down to floor 1 and talk to Sampo near the bar counter. After burning through the dialogues, another enemy will show up. Among all enemies, this one is the toughest as the opponent uses a gilded Phainon card.

Same as before, use the Firefly card to defeat this adversary. To maximize the damage output, utilize the Prismatic Dice and reroll (if needed) to get two pairs of the same number when attacking. If you end up activating the card’s bonus effect, winning will be much easier.

When you are done, finish talking with Sampo to conclude the Legend of the Cosmicon Collective quest. You will receive the Aventurine Card as a reward alongside some Stellar Jade, Credit, and Refined Aether.
